Using Kafka as a (CQRS) Eventstore. Good idea?
...nsumption, after which it
will be discarded to free up space. Kafka's performance is effectively
constant with respect to data size so retaining lots of data is not a
problem.
So while messages can potentially be retained indefinitely, the expectation is that they will be deleted. This doesn...
How is the fork/join framework better than a thread pool?
...up into small evenly sized chunks in one big bang. Say dealing with a some form of hierarchy without balancing.)
Conclusion: FJ allows more efficient use of hardware threads in an uneven situations, which will be always if you have more than one thread.

...te (per the MVC design pattern). Usually you want to avoid putting state information inside a controller, unless it's strictly "presentation" data.
Second, see page 10 of the Stanford presentation for an example of how to programmatically push a controller onto the navigation controller. For an exa...
PHP parse/syntax errors; and how to solve them
... statements into distinct or nested if conditions.
Instead of lengthy math formulas or logic chains, use temporary variables to simplify the code. (More readable = fewer errors.)
Add newlines between:
The code you can easily identify as correct,
The parts you're unsure about,
And the lines which t...
How to limit setAccessible to only “legitimate” uses?
..., if you mean "privacy" to encompass the meaning of protecting sensitive information from disclosure, you are barking up the wrong tree. The way to protect sensitive data in a Java application is not to allow untrusted code into the security sandbox that deals with sensitive data. Java access modi...
How to avoid reverse engineering of an APK file?
...r and device.
When storing values on the device, don't store them in a raw format. For example, if you have a game, and you're storing the amount of in game currency the user has in SharedPreferences. Let's assume it's 10000 coins. Instead of saving 10000 directly, save it using an algorithm like ((...
Why does base64 encoding require padding if the input length is not divisible by 3?
...s are concatenated, it's impossible to recover the original data because information about the number of odd bytes at the end of each individual sequence is lost. However, if padded sequences are used, there's no ambiguity, and the sequence as a whole can be decoded correctly.
Edit: An Illustration...
Where does Scala look for implicits?
...r implicits? I mean implicit because the question never seems to get fully formed, as if there weren't words for it. :-) For example, where do the values for integral below come from?
